Inherited TraitsAcquired Traits

An inherited trait is a genetically determined characteristic that distinguishes one organism from another organism. Some inherited traits are dominant, some are recessive, and some are neither. · An example of an inherited trait in plants may be color of flowers. The color red is dominant over the recessive color white. Pink flowers are a result of a blending of red and white. Other examples of inherited traits may be the shape of seeds or leaves, or the height of the plant. · An example in animals may be eye color. Brown eye color is dominant over the recessive blue eye color. Green or hazel eyes are neither dominant nor recessive. Other examples of inherited traits may be body design, baldness, blood type, or skin color.

Examples of environmental factors that can alter the phenotype of an organism may be temperature, nutrients, injuries, disease, exposure to sun, or living conditions. · Temperature, for example, may affect the number or size of leaves in plants or the color or amount of fur or thickness of skin in animals. · Nutrients, for example, may affect the growth or seed production in plants or the weight or height in animals. · Injuries, for example, may cause scarring in plants and animals. · Disease, for example, may affect the number of branches in plants or body shape in animals. · Exposure to sun, for example, may affect the color of leaves in plants or skin changes in animals. · Living conditions, for example, may affect the leaves, roots and height in plants or the condition of fur, skin, or teeth in animals.
